Are you talking about doing the hinges, drawer slides or handle & knobs?
I used the kreg Concealed Hinge Jig for my door hinges on the cabinets I built. Worked awesome.
I used these for handle and knob placement.
For the drawer slides I used a level and ruler.

By the way the cost is relative to how many you are doing. Will I use the Kreg systrm again, probably not but for the 10 doors that I built and installed using worth every penny.
